论文通过对城市水资源系统的结构分析,指出城市化的产生和发展是造成城市水资源紧缺和水污染的主要原因,而提高城市水资源系统的自我调节能力,加强其反馈结构——循环用水系统和污水回用系统的功能,是城市水资源系统的发展方向,并介绍了国内外在该领域研究的进展。 论文讨论了加强城市水资源系统的自我调节能力——减少用水量和排水量的各种方法,包括:①通过各种行政、经济、教育、宣传手段节约自来水用量;②通过加强冷却水循环、循环用水、污水再生回用、推
Through the structural analysis of urban water resources system, the paper points out that the emergence and development of urbanization are the main causes of urban water shortage and water pollution, and improve the self-regulation ability of urban water resources system and strengthen its feedback structure - recycling water The function of system and wastewater reuse system is the development direction of urban water resources system and the progress of research in this area at home and abroad is introduced. The paper discusses ways to enhance self-regulation of urban water resources systems - ways to reduce water use and displacement, including: (i) saving tap water usage through various administrative, economic, educational and promotional measures; and (ii) Sewage reuse, push
